Upload a PDF, choose a password, and download a new copy locked with it. Everything happens in your browser; nothing is uploaded to any server.
Upload & Set Password
This works on a regular PDF. Already-protected PDF? Unlock it first with our PDF Password Remover, then set a new password here.
Note: The new PDF is rebuilt page-by-page as images, so it will look identical to the original but its text won't be selectable or searchable anymore — a necessary trade-off for adding real password protection fully in your browser with no server involved.
